We want to know what kind of life is most worth living. And long ago, Aristotle said that what all people seek is happiness. But what is happiness?↵
There are different views on this: objectivist, subjectivist, and combination theorist. First, according to objectivists, who follow Plato and Aristotle, happiness is not a subjective state like pleasure or contentment, but the only ideal of human nature. They say that we are truly happy when we live according to reason, which is a uniquely human function.↵
The subjectivist view of happiness is explained as follows; Happiness is in the eye of the beholder. The only person who knows or decides whether I am happy or not is me (even if others criticize my lifestyle, if I feel happy, 1 am happy).↵
The views of combinatorial theorists try to integrate the views of objectivists and subjectivists. According to Rawls's concept of plan-of-life, there are many different life plans open to each person. What is important is that the plan should be freely chosen by the person and that the person be successful in realizing his or her purpose. (This view is strikingly subjective in that it perceives the person as an autonomous chooser of purpose or plan.) There are also primary goods that are essential to any worthwhile life plan for the individual. These are rights and liberties, self-respect, intellect and imagination, and so on. The primary goods are the core of any life plan, from which the life plan must be derived.↵
This idea of happiness is worth pondering. Even the same life has different values depending on which theory you look at it from. Which theory seems closest to the truth? It's up to you to decide what a good life, what happiness is.
